SHUTTLE-SPINDLE.

SPECIFICATION forming part of Letters Patent No. 224,790, dated February24, 1880.

Application filed August 25,1879.

To all whom it may concern: Y

Be it known that we, GEORGE E. MoRRILL and FREDERICK W. SAWYER, ofGardiner, in the county of Kennebec and State of Maine, have inventedcertain new and useful Improvements in Shuttle-Spindles; and we dohereby declare the followingto be a full, clear, and exact descriptionof the invention, such as willenable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

Our invention relates to shuttle-spindles, and is designedto provideimproved means for holding the cop securely in place while the shuttleis working, and, after the yarn is used, permit the tube to be removedand a full tube substituted therefor.

The improvement consists in the construction hereinafter described andclaimed.

Referring to the drawings, Figure 1 is a perspective view, showing thespindle thrown out from the shuttle. Fig. 2 is a plan view, showing thespindle in closed position. Fig. 3 represents detail views of thespindle and cam, and Fig. 4: is a detail longitudinal section' of thespindle. I

The spindle A is provided with a longitudinal groove, to, in which therotary cam B fits, the latter consisting of a bar, preferably made ofsteel and of greater width than depth in its transverse sectionaldimension. Its working edge is provided witha series of indentations, b,which cause itto engage more securely with the cop, which is held by thecam in position on the spindle. The heel of the latter is secured to theshuttle by a pivotal bearing, 0, and its side is grooved, as shown at d,to receive the heel of the cam. A transverse circular recess, c, in thespindle-heel receives an annular shoulder, f, formed on the cam-heel,and

1 thereby said cam is prevented from having longitudinal movement in itsgroove. The opposite extremity of the cam is provided with an endprojection, g, which fits in a corresponding eye in the end of thespindle-groove nearest the point of the spindle, and thereby I the camis secured against accidental displacement from its groove.

The heel of the cam is provided with a lateral projection, h, which fitsin a slot, 1, formed in the corresponding portion of the shuttle, theadaptation of parts being such that when the spindle is swung on itspivotal bearing in or out of operative position said cam is automatically rotated.

A plate, 0, is provided, which prevents the shuttle from becoming undulyworn, as would be the case if the heelprojection engaged directly withthe wood of the shuttle.

When the spindle is thrown out of operative position, as represented inthe first figure of the drawings, the cam is rotated so thatit does notproject laterally beyond the circular contour or outline of the spindle;but when the spindle is in operative position, as shown in the secondfigure, the cam projects laterally beyond the circular outline of thespindle, and its working edge is adapted to engage securely with thecop-tube. Thus the cop is held firmly in place on the spindle while theshuttle is at work, and when the yarn is exhausted from any one tubea-new one can be readily substituted therefor.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is-- 1. The combination, with a shuttle-body having one end provided with an interior side slot and a pivotalspindle formed with a groove in the main portion of its length andextending across its heel, of a rotary cam fitted in the groove andhaving its extremity projecting beyond the spindle-heel, said projectingextremity being provided with a lateral arm adapted to engage with saidside slot of the shuttle, substantially as set forth.

2. The combination, with a shuttle'body having a centrally-recessed end,a metallic slotted plate fitted in the latter, and a. pivotal spindlehaving a groove formed in the main portion of its length and across itsheel, of a rotary cam fitting in the groove and having its extremityprojecting beyond the spindle-heel, said extremity being provided with alateral arm adapted to engage with said slotted plate, substantially asset forth.

3. The combination, with a shuttlebody having a centrally-recessed endand a metallic slotted plate fitted in the latter, of a pivotal spindleformed with a groove in the main portion of its length and across itsheel, and also In testimony that we claim the foregoing formed with atransverse recess in its heel, towe have hereunto set our hands this15th day to gether with a rotary can] fitting in said spinof August,1879.
